Both PFA and PTFE are raw materials for Teflon wire use, PFA characteristics are corrosion, and the friction coefficient of PTFE features is very low, then what is the difference between PFA PTFE?
Appearance: PFA translucent, PTFE pure white opaque.
Temperature resistance: PFA-200 degrees - + 260 degrees, PTFE-200 degrees - +250 degrees.
The shape of the raw material: PFA is granular, and PTFE is powdered.
PTFE Teflon wire: when it is in a high-temperature environment of 327 ° C and below, the PTFE wire will not be affected, even when the temperature is higher than the melting point, the outer insulation does not drop down, and when the temperature is lower than the melting point Outer insulation will restore the original state.
PFA Teflon coated wire is in a short period of 320 ° C in a short time, and the insulating layer will combustion, and drip down.
Price: PTFE wire is more expensive than PFA Teflon wire
